I'm trying to understand the relationship between the DG and the DAG. I created two objects, one translated a bit from the origin, and then did Mesh->Combine. A new transform node for the combined mesh is created, and the original transform nodes are still in the DG. I can change the relative position of the objects by changing the original transform nodes. This all makes sense.
What I'm puzzled by is that a new transform transform2 has apparently been inserted between the original transform pCylinder1 and the original mesh pCylinderShape1. (See screenshot below.) This new transform is just set to be the identity (zero translation, etc.). But I can change it if I want, and it works as expected, and the resulting transformation is just the composition of the two (product of the respective matrices). At least from a linear algebra perspective, transform2 seems redundant.
So my question is, why was transform2 created (or where did it come from, if it already existed)? If I want to change the relative positions of the two objects, which transform makes more sense to use?
Also welcome pointers to additional documentation to read. Thank you.
